Thread: Op amp motor driver circuit

Tweet

Hi all,
I finally got all the bugs out of this thing. This is a circuit that can drive various talking props like Gemmy skulls and such. The prop's jaw motor is connected as shown and you can use a CD or MP3 player as the audio source. The parts are cheap, and most can be found at All Electronics except for the TLE2022 chip (Digikey and Mouser have it). It runs on a 9 volt battery or regulated wart. It can operate on a 4AA pack, but may not be able to drive the motor properly due to the voltage drop across the circuit. The board has an audio out jack for connecting a set of computer speakers. I'm working on a sourced parts list and will post it soon. The pic is kinda small, so I'll replace it with a larger one tomorrow.

An update on this circuit - I sent the schematic to Jeff Wheat (a haunters best friend) at www.simplecircuitboards.com and he burned a board for me to test. I built it out and it works perfectly. Jeff will be adding this item to his product line; the price is $7.00 for one board ($2.00 shipping) and $5.00 each for additional boards in the same order.
I'm putting together a parts list (many thanks to Halstaff for his previous parts list) and I'm trying to get everything from one source (DigiKey) to reduce shipping costs. Right now, the total cost of the board is <$12.00 without shipping charges. It'll take me some time to cross-reference the parts but I should have the list posted in a couple of days.
More to come...
